4. Interfaces
4.1. High-Speed 2.0 USB Interface
4.1.1. USB-Power
The USB communication port can be used for powering the PE60_2 electronics, provided it's connected to an active USB hub capable to draw up to 500 mA current at 4.4V - 5.25V.
Configuration with higher current need should be external powered.
Passive USB hubs do not provide sufficient power. In this case, the electronics has to be powered externally.
The OR gated low drop out power circuitry switches automatically over to USB powering or external power, which voltage is ever higher.
4.1.2. USB Configuration
The USB 2.0 High Speed communication is performed by a USB CDC Class virtual serial port.
The transmission speed of 115 200 bit/s is necessary to fit the virtual serial COM-port protocol. The protocol settings are 8N1 (8 bit data, no parity, 1 stopbit) and no handshake. Data transfer will be done with USB high speed (480Mbit/s) independent of the virtual com port speed settings. The effective data rate can reach up to 130Mbit/s.
Users program or the OS must provide enough communication queue memory in case of huge amount of data to be transmitted at once.
USB drivers are already included in Windows 10 and actual Linux Distributions by default. Drivers for Windows 7 and 8/8.1 are available from JETI.

4.6. Universal Interface
All Signals mentioned in Chapter 2 are available on the 34Pin P-UniCom connector. It enables a 34-Pin 0.5mm pitch FPC-Cable connection for a universal connection to customer equipment or Jeti add-on boards. It is
established on our different electronic platforms for easy interchangeability.
If only some of the signals are needed, it is possible to use a decreased range (e.g. Pin 1-16) with a reduced FPC-Cable Pin count.
4.7. Shutter/Lamp Connector
The PE60_2 Electronics supports firmware generated Shutter/Lamp output signals for control of peripherical hardware with the following pinout. Please refer to “OP_Firmware_Commands_Specfirm_ PE60.pdf” for more information’s. The connector is a 4pin WR-WTB 653104131822 SMD component with 1.25mm pitch of wuerth-electronics.

5. Power Supply
5.1. USB-powered
The USB communication port can be used for powering the PE60_2 electronics, provided it's connected to an active USB hub capable to draw up to 500 mA current at 4.4V - 5.25V.
Configuration with higher current need should be external powered.
Passive USB hubs do not provide sufficient power. In this case, the electronics has to be powered externally.
The OR gated low drop out power circuitry switches automatically over to USB powering or external power, which voltage is ever higher.
5.2. 5V external supply
Beside the standard USB power supply which is described above, an external voltage source can be applied to the P-Vext2 connector with the polarity marked on the board.
Exceeding the recommended voltage range and ripple may increase the noise of the video signal but should still work if it fulfills the minimum requirements.
5.3. 7-28V external supply
This Option includes a 5V fixed output voltage dc/dc step down regulator with up to 2.5A output current. The converter allows to use the electronics with supply voltages between 7V and 28V and provides a sufficient low output voltage ripple (typ. 10mV) and a peak efficiency up to 95%.
